What is the difference between a common name, IUPAC name, a name in an international journal, and a name in an American journal? I understand how to do IUPAC names, but then I am confused at the rest.
A 0.479 g sample of nitrogen, oxygen or neon gas occupies a volume of 265 mL at 157 kPa and 20?C. What is the molar mass and identity of the gas
The only thing that is supplied to you is 1M Tris (pH 6.8) and 1M NaCl. You have full access to all the deionized H2O you may need. Plus 3 M HCl, 40 g/mol of NaOH pellets, and a pH meter.
a block of aluminum with the volume of 96.5 g absorbs 65.3 J of heat. If the initial temperature is 31.2 degrees celcius, what is the final temperature.
5x10^3 moles of an ideal gas are held in a container of volume 0.0124 dm^3 and surrounded by a thermostat at 298K. The gas is allowed to double in volume against a constant external pressure of 1.0 atm
The rate law for the decomposition of ozone to molecular oxygen: 2O3(g) --> 3O2(g) and the mechanism proposed for this process is: O3 O + O2 and O + O3 --K2--> 2O2. Derive the rate law in terms of K1, K-1 and K2.
sulfur dioxide was allowed to effuse through a small opening under constant pressure conditions. It required 179 s for 1.00 L of this gas to effuse. Calculate the effusion time of arsine (AsH3) under identical experimental conditions

How much heat is required to raise the temperature of 7.50 grams of water from 10 degrees celcius to 55 degrees celcius
A compound is found to be 26.95% sulfur, 13.43% oxygen, and 59.61% chlorine by mass. What is the simplest formula of the compound?
How many grams of CO are needed to react with an excess of Fe2O3 to produce 558 g Fe? The equation for the reaction is: Fe2O3(s) + 2 CO(g) → 3 CO2(g) + 2 Fe(s)
Calculate the work done (in J) on the surrounding atmosphere (1atm pressure, 25.5 oC ) by the evolution of hydrogen in the subsequent reaction. State any assumptions you have made.
Which metal hydroxide will precipate first? Why? Ksp Ni(OH)2 = 6.0x10-16 Ksp Ce(OH)3 = 6.0x10-22 Ksp Cu(OH)2 = 4.8x10-20
